Ocular toxocariasis caused by Toxocara canis in an adult dle. Toxocariasis is a zoonosis caused by the Toxocara canis and Toxocara cati nematodes larvae. These are intestinal parasites found in canids and felids, respectively. Retinal detachment in the left eye was diagnosed by ultrasound.

The ophthalmology service made a differential diagnosis of retinoblastoma and pars planitis. Symptomatic management was initiated with oral and topical corticosteroids, obtaining dn improvement, although loss of visual acuity persisted.

Coexistence and cohabitation of the patient with pets dogs and cats was an important factor to consider ocular toxocariasis. Complete blood count revealed mild leukocytosis and lymphocytosis without eosinophilia. Management with ophthalmic and systemic corticosteroids, albendazole and vitrectomy was initiated.

The vitreous band was released by means of surgery, making the diplopia disappear, although residual peripheral granuloma persisted and will be operated by ophthalmology.

Knowledge on ocular toxocariasis is important for physicians because it might be mistaken with retinoblastoma, a malignant neoplasm that may require enucleation of the eye. Toxocariasis is a neglected parasitic disease that affects mostly poor and isolated communities in low-income countries. For this reason, little attention has been paid een this condition in terms of surveillance, prevention and control.

In general, humans are infected through ingestion of embryonated eggs in contaminated soil and, therefore, contaminated hands. In perroa, children of preschool and school age are the most affected, although adults may also develop the disease.

The purpose of this work is to report a case of ocular toxocariasis in an adult patient, highlighting the limitations found when establishing the correct diagnosis in adults, even though this is one of the most common zoonotic infections in the world.

The relevance of this clinical case is that it provides specific clinical signs of ocular toxocariasis that help to achieve a diagnosis using complementary serological methods that provide evidence on Toxocara infection to minimize anatomical and functional sequelae. The patient presented retinal detachment in the left eye diagnosed by ultrasound.

She consulted with ophthalmology, where a differential diagnosis of retinoblastoma and pars planitis was made. Symptomatic management was initiated with oral and topical corticosteroids. She was referred to the Instituto Nacional de Salud National Health Institute due to suspicion of ocular toxocariasis.

At the time of consultation, she had been living for 6 months with a dog and two kittens that had not been vaccinated nor dewormed. The woman said that she occasionally took her pets to the park, where they were in contact with soil and feces and reported feeling better with the drugs prescribed by ophthalmology, although her visual acuity continued to be affected.

Upon physical examination, her vital signs were within the normal range and without fever. Ophthalmological examination showed visual acuity in the right eye sc: Hyperemic tarsal papillae were also observed in both eyes. Ophthalmoscopy in the right eye was normal, while a peripheral granuloma and a fibrous band pulling the macula were observed in the left eye. The rest of the physical examination did not show any alterations. When analyzing the complete blood count made on March 9,slight leukocytosis and lymphocytosis without eosinophilia were observed.

However, the values returned to normal after the symptomatic treatment ended on June 14, Table 1. The results of the coprological and partial urine tests were normal. In addition, anti- Toxoplasma gondii and anti- Taenia solium cysticerco antibodies were negative, as well as the VDRL. Results of blood counts at two different times.

Case reports

Own elaboration based on the data obtained in the study. The enucleacuon required surgical management with vitrectomy in the left eye to release the vitreous band, making the diplopia disappear.

However, residual peripheral granuloma persisted and will be operated by ophthalmology. Hygiene recommendations were provided to the patient and her relatives, the consumption of well-cooked meats was suggested and control was scheduled at 1 month.

Knowing about this clinical case is relevant to the medical and scientific community for three reasons: Toxocariasis has been described more frequently in children of preschool and school age due to the permanent presence of risk factors in this particular age group. Definitive diagnosis of ocular toxocariasis is obtained by demonstrating the presence of migrating larvae in the biopsies of the compromised tissues, which is rather exceptional since it is an invasive procedure.

Coproparasitological examination is not useful because the parasite is unable to mature inside a human host. On the other hand, although eosinophilia is an important marker of systemic toxocariasis, it is not usually observed in ocular form 1,3but its presence may indicate the coexistence of both forms of toxocariasis in the same patient.

There are four clinical presentations of ocular toxocariasis, but dl two pjo more common: Diagnosis of ocular toxocariasis is based on the identification of particular signs and symptoms; it should be supported by a complete clinical history that provides a detailed report of socioeconomic background and should be complemented by an indirect ELISA test performed on a serum sample or vitreous humor.

This process is carried out in order to avoid erroneous diagnoses such as retinoblastoma and other granulomatous diseases of the eye. Enucleacoin ocular toxocariasis is a neglected and global disease, it is important to implement prevention and control measures to reduce the prevalence of this parasitic disease in the population.

For this purpose, awareness must be generated in the community about this type of preventable diseases oj the promotion of good hygienic practices such as hand washing, identification of transmission sources and reduction of exposure to etiological agents. Furthermore, it is necessary to develop programs for deworming pets, both dogs and cats, in order to control the transmission of this disease.
